PRODUCT FEATURES AND CONTROLS

PRIMARY AIR CONTROL

The primary combustion air delivery is controlled by the Primary Air Control Assembly (The control knob is lo- cated above the fuel door). The heat output can be con- trolled by sliding the handle to a higher or lower heat output setting (See Care and Operation Section – Pri- mary Air Control, page 13). The fuel, the amount of heat and burn times desired, the type of installation are all variables that will affect the control setting. The same control settings in a variety of installations will produce different results. You will need to try different settings so you can learn how much heat to expect and how long the fire will burn.

CATALYTIC COMBUSTOR

How it works: From 5 to 30 percent of the chemical energy contained in every log escapes up the chimney when wood is burned in a conventional stove. The catalytic combustor is designed to make use of this en- ergy, converting it into useful heat as it lessens chimney creosote build-up and air pollution. The catalytic com- bustor consists of a durable temperature resistant ce- ramic composition, which is extruded into a cellular, or honeycomb, configuration. After extrusion, this ceramic monolith is fired and then covered with a noble-metal catalyst. When wood smoke contacts this catalyst, chemical changes occur that causes the smoke to ignite at temperatures around 600° F. Normally, smoke will ignite and burn only at temperatures around 1000° F.

CATALYTIC BYPASS DAMPER CONTROL

The operating handle of your Bypass Damper Control is located on the front of the Stove Flue Collar. By moving the Bypass Damper Control the operator can route the exhaust either through the Catalytic Combustor (pushed in) or directly up the flue (pulled out). When starting a

fire or refueling, the bypass damper control handle

should be pulled out. Once the fire is established it should be pushed in.
